After updating my Iphone 4 to IOS 7.1.1 the phone bricked and can't be restore it shows error 2

After updating my Iphone 4 to IOS 7.1.1 the phone bricked, I tried restoring and it can't be restore because an error has occurred (error 2) I have follow the steps to troubleshoot and resolve the problem, but I havent' been succesful. All the forums I visited they say error 2 can be resolved by modifiying the security settings or disabling third party security software, changing teh cable etc. I have a MacBook Pro and don't have any third party security software. I will appreciate your help. Thanks
